Go Brew Fish

Setting up Go on MacOS with Brew using Fish shell. This guide expects that you are already using fish shell on Mac and are comfortable using the command line. This guide does not cover setting up Brew either.

Install Go via Brew

brew install go

Configure Go environment.

Add the following to your ~/.config/fish/config.fish file.

GOPATH is where you will have your Go code. I have chosen to use my Development directory in the home directory. Later we will make a new Go directory.

GOROOT is where go was installed by brew.

set -x GOPATH ~/Development/Go
set -x GOROOT (brew --prefix golang)/libexec
set -x PATH $PATH $GOROOT/bin $GOPATH/bin

Create a new directory for our Go code.

mkdir -p ~/Development/Go/src

Source the config file or open a new terminal window.

source ~/.config/fish/config.fish

Testing

Now create a hello directory for testing and change to that directory.

mkdir -p $GOPATH/src/hello
cd $GOPATH/src/hello

Create and edit hello.go in the newly created directory with the sample code below.

package main

import "fmt"

func main() {
	fmt.Printf("hello, world\n")
}

From within the hello directory, run the following

go run hello.go

If everything worked, you should see “hello, world” returned.
